<br>
I'm guessing you checked the energy spectrum to look for the third gamma? Just taking a quick look at your macro I think you are not seeing it because you limit the energy window for your singles to 800 keV. This way events from the 1275 keV gamma will not
be stored in your output file.<br>
<br>
Best regards,<br>

<div>For people to help you, you should tell the mailing list how you determined that it is not producing the gamma ray.</div>

I am using gate v6.2 for the simulation of our PET system, and want to<br>
use Na22 as the source. My code is in the attachment. It seem not to<br>
produce the Gamma. I do not know whether there is something wrong with<br>
my source or my physical process. Could anyone send me a complete<br>
instance with Na22 as the source? Thanks a lot! Best!<br>
